UPDATED FORECAST FOR THE ROCKIES AND A QUICK LOOK AT THE EXTENDED
MARCH 4, 2017. 10PM UPDATE
I am sorry for the late posts! I was up at 4:30 AM and driving up Little Cottonwood by 5:30 AM. If you still up can chase to the Wasatch or Tetons you may still be able to sneak another powder day in for Monday. My forecast for 11-16 inches held true for most resorts in Utah especially combined with an additional 4-8 on my evening post (16-24 inches for storm totals). My day totals were short in LCC this morning. Snowbird is up to 23 inches while resorts in Big Cottonwood saw less. My 30% chance of higher amounts held true! This did not surprise me as winds from the NW favors LCC, versus BCC. Winds initially were from the SW last night so amounts early in the storm were pretty close between the 2 canyons. Alta/Snowbird put the firehouse on this morning with several periods of 1-2 inch per hour snowfall just prior to the lifts opening today. Here is a picture of the base area at Snowbird that I snapped around 11AM. Notice the full burial in the background. The Snowbird Center was over the knees this morning at 9AM. The report of 23 inches late in the day was pretty accurate (May have been deeper in spots).
Today was simply epic in every way with Snowbird Safety and Patrol popping upper mountain ropes on the 1st tram this morning. Kudos to the patrollers and snow safety dispatch. The road was a nightmare with average commute times up LCC of 3-4 hours! That never happened in the old days! The severe traffic and slow speeds kept the tram line to a short line for most of the early morning hours. More terrain will open on Monday so if you missed today, you still have some hope of waist deep powder.
In looking at snow telemetry it appears that Grand Targhee had a full burial (Not surprising with cold air, moisture and the perfect NW wind direction). They reported 9 inches last night and automated data looks like another 8-10 fell during the day! Snow is still falling in the Tetons. Models show moderate snow continuing into the morning hours Monday.
Colorado that never excited me will see 3-7 inches in most mountain locations for Monday. Most snow came in late Sunday. Steamboat is up to 7 inch storm totals. Snowmass is between 4-6 with Vail not far behind.
The extended forecast looks unsettled for the Pacific Northwest late in the week (Oregon is initially favored). The northern Panhandle may also score. The Sierra range north of I-80 may also see snow late week. Chases may include OR, WA by Thursday. Looking at the following week it’s possible the entire Sierra Range nab another deep dump.
